Siemens 'Helios' Model Modular signals following completion of 'The Big Dig' in the east of the city center. For reasons previously unknown, the council chose Siemens Helios and PEEK's Elite model Modular head for the re-generation works, rather that thier beloved TSEU 'MSH' Model signal. This may be due to the fact TSEU no longer show the 'MSH' Model on thier web page, so it may have ceased manufacture of this type of signal head. This pair of signals show arrow aspects, the left having ahead symbol and the right having right arrow symbols.
